Xbox Live app?

[DaBrode]

I was browsing through the various apps people have created and uploaded for Windows Mobile and couldn't help but think it would be kinda neat to have access to my Xbox Live accounts and acheivments as well as the lists of latest downloads etc. Now I know this is all available online already but an app not unlike the facebook.cab I've seen out there would be really cool. Not groundbreakingly useful, but cool.

Is there one out there I haven't found or would anyone else jump on the bandwagon of wanting one? It's beyond my current expertise but if there is a common desire for it...perhaps a guru will take up the cause!
